Jooki is the favorite 3-to-9 years old educational toy that fosters their imagination with music & storytelling, and helps build the core foundation for their future. Jooki is the only high-quality speaker that gives kids safe, screen-free access to streaming audio content. Grown-ups create playlists from Spotify (or their own MP3) and associate them with a Jooki figurine in a few clicks with the Jooki app. Next, kids just place that figurine or token on Jooki to start the playlist… or lift it to pause, stop or change. Children grow fast and their needs change just as quickly. Parents will easily reprogram Jooki tokens and figurines to share new inspiring audio content with their kids. Jooki will play Spotify playlists when connected to Wi-Fi and MP3 playlists anytime, anywhere. More than one phone can connect and program Jooki tokens/figurines. From the Jooki app, parents will be able to connect Jooki to a new Wi-Fi network (Jooki will remember up to 8 networks), connect Jooki to a wireless headset or speaker, enable or disable the volume limitation compatible with 3-year-old toy safety standards, and turn off Jooki remotely.

Verdict
The clearest difference is review sentiment: LEGO® Boost at 66% against Jooki's 20%. LEGO® Boost also leads on rating (4.6 vs 1.8) and ads (none vs shown). Jooki's advantage is update cadence (every 3 weeks vs every 3 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Written reviews point the same way: 66% of LEGO® Boost's written reviews are positive against 20% of Jooki's.
LEGO® Boost ships an update every 3 months, Jooki every 3 weeks. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
